E-stop
(switch 1 in position 0)
With switch 10 the maximum number of e-stop loops is selected. Open
(unused) inputs (S_1/S_2 and S_3/S_4) have to be linked with a wire
bridge.
K1 and K2 can only be activated, if all e-stop buttons are released. The
function diagrams show only the action of one e-stop button. We pretend
that the others are closed.
When the unit is used with 2-channel e-stop loops, it checks the state of the
inputs. If both channels have different signals for more then 50 ms the outputs
K1 and K2 are switched off and the unit gives failure code 7. This failure is
stored and can only be reset by disconnecting the auxiliary supply.
